The following bug has been logged on the website:
Bug reference: 19089
Logged by: Jevgeni
Email address: mckeny@gmail.com
PostgreSQL version: 18.0
Operating system: DSM for Synology NAS
Description:
Dear postgres dev team,
to begin with: I am just a semi-professional synology user. I have tried to
go through your documentation, however not everything is clear for me, thus
I decided to report a bug even though there might be a solution described
there. Please feel free to wait for a more precise bug report, but I wanna
do my part to improve postgres and have to place my issue.
Now to the bug: My goal was to install a paperless ngx version with a
postgres DB on an synology NAS (DS920). With the following
docker-compose.yml I have downloaded and installed the newest version 18.
Since the synology has a container Manager as app, I dont have to dive into
any linux "sudo" language, just import an docker-compose file created by the
community and thats it.
Part of docker-compose.yml for postgres
"db:
image: docker.io/library/postgres:17.6
restart: unless-stopped
volumes:
- /volume1/docker/paperless/pgdata:/var/lib/postgresql/data"
When trying to start the container, I faced the following mounting issue:
"Start container paperless-db-1 failed: {"message":"failed to create task
for container: failed to create shim task: OCI runtime create failed: runc
create failed: unable to start container process: error during container
init: error mounting \"/volume1/docker/paperless/pgdata\" to rootfs at
\"/var/lib/postgresql/data\": change mount propagation through procfd: open
o_path procfd: open
/volume1/@docker/btrfs/subvolumes/f09606bf50bd944d6fa6cb04b29702120c1639298878114955ae09f6cfa5a0d4/var/lib/postgresql/data:
no such file or directory: unknown"}."
Changing to the version 17.6 fixed the issue.
Thanks a lot for the job you are doing!
